The panels are equipped with functional parts such as glass door lifting switches, as well as decorative strips to beautify the interior environment. Therefore, it has many accessories and the manufacturing process and surface treatment process are also relatively complex. Generally, the base material is injection molded, and the product surface is painted and electroplated. The decorative strips are usually assembled by clamping and welding.

[0003] In the prior art, the switch panel is usually processed by spray painting, and the decorative strip is usually processed by electroplating. A plug-in block is provided on the switch panel. The decorative strip is provided with a plug-in hole for plugging with the plug-in block.

[0004] Regarding the above-mentioned related technologies, the switch panel is usually made of ABS material, and a smooth surface is formed after painting. The surface of the decorative strip is usually electroplated with metal chrome. The surface roughness of the metal chrome is basically the same as the surface smoothness of the switch panel after painting. When the two are abutted together, since the switch panel is made of injection molding technology, the product dimensional stability is poor and the deformation is large. After assembly, a gap is easily generated between the switch panel and the decorative strip, causing the switch panel and the decorative strip to move relative to each other, which will emit a sharp abnormal noise, affecting the use experience of the switch panel and the decorative strip, and it is urgent to improve. Summary of the invention

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The decorative strip is installed on the switch panel. When the rough surface and the smooth surface are in contact, the relative friction surface between the two contact positions can be reduced, thereby reducing the generation of abnormal noise and improving the comfort of using the switch surface; 2.

With such a design, the relative friction surface of the contact position between the smooth surface and the rough surface is reduced, thereby reducing the generation of abnormal noise and improving the comfort of using the switch surface.

The limit slider 7 is provided with a deformation gap 8 on the side close to the switch panel 4. When the limit slider 7 is plugged into the plug-in block 3, the side walls of the limit slider 7 can be pressed against both sides, so as to achieve the purpose of fixing the decorative strip 2.
